“…however, not be excluded that trapped electrons may also be able t o react with a solute molecule before they are thermally released into the V,, level. This may occur in liquids of Iow mobility in which the electron spends most of its time in the trap and where its optical absorption has even been observed (13,14). Reactions of a localized electron may occur via tunneling to the acceptor molecule.…”

A. HENGLEIN. Can. J. Chem. 55.21 12 (1977). Reactions of free electrons in the gas phase, of quasi-free electrons and solvated electrons in dielectric liquids, of hydrated electrons in water, and of electrons originating from an electrode in contact with a solution are among the great variety of electronic processes in chemistry. It 1s the purpose of this paper to describe a few phase effects. Reactions of electrons in dielectric liquids will be discussed with respect to the corresponding processes in the gas phase. Furthermore, certain aspects in the transfer of an electron from a hydrocarbon phase into the aqueous phase will be dealt with. The processes will be described in terms of electronic redox level distributions of the acceptor redox systems.

“…RTILs with TFSI as the anion have been reported to have very low dielectric constants (Wakai et al, 2006), and have been classified as non-polar solvents. The values of G(e À ), however, were considerably higher than the value of about 0.1 for non-polar solvents such as hexane (Baxendale et al, 1971). Thus, the RTILs are expected to have a similar effect on the decomposition of CP as polar solvents.…”

“…This value is to be compared with a value of 1 X 1012 M™1 sec™1 obtained for electron scavenging by biphenyl and carbon tetrachloride in «-hexane36 and a value of 1012 M™1 sec™1 obtained for electron scavenging by pyrene and carbon tetrachloride in methylcyclohexane. 37 (3) In a recent study Infelta and Schuler38 have estimated from electron scavenging competitive studies an electron transfer parameter ß = feern/X. A typical value of this pa-, rameter is 0.5 M™1 (CH3C1™ + SF6 -CHSC1 + SF6™).…”

Publication costs assisted by Carnegie-Mellon University and the U. S. Atomic Energy Commission Charge scavenging kinetics established previously to account for the time dependence of the biphenylide ion in pulse-irradiated biphenyl-cyclohexane solutions are extended to the formation of excited states in such solutions. It is shown that given a particular reaction scheme one can describe the concentration dependence of the excited states in the steady-state radiolysis as well as their time dependence in pulse radiolysis. From the comparison of the predicted behavior and the experimental data available from the literature it is concluded that the triplets and singlets originate predominantly in the three different recombination processes: S+ + e, S' + RH+, and S~+ S+. Moreover , the constant characterizing the ion recombination processes in the pure solvent, can be interpreted to be ~2 X 10n sec-1 which indicates that half of the original ions recombine in ~3 psec. This in turn indicates that the rate constant for electron scavenging by biphenyl in cyclohexane is ~3 X 1012 M_1 sec-1. Implications of these constants are discussed.
